Menu Flow

Compatibility entry. Delegate screen/page transitions and pause policy to ui-flow, focus/input handoff to ui-hud-focus, semantic controls to input-design, and browser lifecycle details to browser-input when applicable.

Do not maintain independent physical key, Pointer Lock, multi-touch, hitstop, shop, or inventory rules here. Preserve legacy intent only long enough to select the real owner:

Acceptance

A request routed through menu-flow resolves to the same project screen/focus/input data as a direct request to the true owners. No second pause/input grammar evolves in this compatibility file.
